可编辑QTableView中的Pandas df:删除复选框 [英] Pandas df in editable QTableView: remove check boxes

问题描述

我有一个熊猫数据框，我想在QtableView中展示它并使之可编辑.我创建了以下模型，但是由于某种原因，输出在每个字段中都有复选框.我该如何摆脱它们?

I have a pandas dataframe that I would like to present in a QtableView and make it editable. I have create the below model, but for some reason the output has checkboxes in every field. How can I get rid of them?

出局看起来像这样:

The outout looks like this:

这是用于制作qtavleview中显示的熊猫数据框并使其可编辑的模型(我正在使用PySide)

And this this is the model that is used to make the pandas dataframe shown in a qtavleview and make it editable (I'm using PySide)

class PandasModelEditable(QtCore.QAbstractTableModel):
    def __init__(self, data, parent=None):
        QtCore.QAbstractTableModel.__init__(self, parent)
        self._data = data

    def rowCount(self, parent=None):
        return len(self._data.values)

    def columnCount(self, parent=None):
        return self._data.columns.size

    def data(self, index, role=QtCore.Qt.DisplayRole):
        if index.isValid():
            if role == QtCore.Qt.DisplayRole or role == QtCore.Qt.EditRole:
                return unicode(self._data.iloc[index.row(), index.column()])
        return unicode()

    def headerData(self, section, orientation, role=QtCore.Qt.DisplayRole):
        if role != QtCore.Qt.DisplayRole:
            return None
        if orientation == QtCore.Qt.Horizontal:
            try:
                return '%s' % unicode(self._data.columns.tolist()[section])
            except (IndexError,):
                return unicode()
        elif orientation == QtCore.Qt.Vertical:
            try:
                return '%s' % unicode(self._data.index.tolist()[section])
            except (IndexError,):
                return unicode()

    def flags(self, index):
        return QtCore.Qt.ItemIsEnabled | QtCore.Qt.ItemIsSelectable | \
               QtCore.Qt.ItemIsEditable

    def setData(self, index, value, role=QtCore.Qt.EditRole):
        if index.isValid():
            self._data.iloc[index.row(), index.column()] = value
            if self.data(index, QtCore.Qt.DisplayRole) == value:
                self.dataChanged.emit(index, index)
                return True
        return unicode()

删除QtCore.Qt.ItemIsSelectable并不能解决问题，因为它似乎没有效果.

Removing QtCore.Qt.ItemIsSelectable does not solve the problem as it doesn't seem to have any effet.

推荐答案

您从data和setaData返回错误的默认值.前者应返回None(因此您可以删除最后一行)，而后者应返回False.

You are returning the wrong default values from data and setaData. The former should return None (so you could just remove the last line), whilst the latter should return False.
